Now buried under the rubble: hopes fade of finding more survivors in a building collapse in Bangladesh.

As Apple's iTunes turns 10, we look at what the next decade might hold for the digital music industry.

And is she tough enough to break the sound barrier? We find out when Anna Coren takes us on an exclusive look inside South Korea's aerospace training program.

Now the death toll has risen in that building collapse on the outskirts of the Bangladeshi capital. 397 people are now confirmed dead, hundreds are still missing, nearly 3,000 people have been pulled out alive since the nine story building collapse five days ago. And crews are now using heavy machinery to remove the wreckage, suggesting that the hunt for survivors is drawing to a close.

Now meanwhile, the owner of the Dhaka building is the latest person arrested in the collapse. And police say that Sohel Rana was caught trying to flee the country. He was arrested on Sunday after a four day manhunt. Reuters reports that he made it as far as the border town of Benapole near India, but police sent him back to the capital where he reportedly will face charges.

And we can head now to CNN New Delhi where Sumnima Udas is covering the story for us. She joins us now live. And Sumnima, the hunt for survivors, is it still ongoing?

SUMNIMA UDAS, CNN INTERNATIONAL CORRESPONDENT: Kristie, hopes are really fading very fast, but the rescue workers say they're still very much in that search and rescue mode. It's quite amazing, they've already been able to pull out more than 2,700 people alive. And just over the weekend on Sunday they were still able to pull out about four people alive.

Now there's also a woman that they found late on Sunday night. She was actually caught amid two huge slabs of concrete. And as they were trying to pull her out a fire broke out, but by the time the fire had been put out the rescue workers could not find her. The army officials there say they're hoping for a miracle and still looking for her.

So amazing stories like this have been emerging. There was another man again caught amid two massive slabs of concrete. He's been yelling -- or he was yelling over the weekend crying out for help. Everyone could see him, everyone could hear him, but they were just not able to pull him out.

The scenes of complete desperation, really, Kristie. But a huge crowd of people have been outside that building collapse site. They're really been since Wednesday. They're mostly family members still looking for their missing loved ones. They've been there, again, since Wednesday. Many of them are families of migrant workers. Remember, these are migrant workers who come into Dhaka to work in these garment factories. And they say they will only go back once they know what's happened to their missing loved ones -- Kristie.

LU STOUT: Wow. Heart and heartbreak at the site of this building collapse.

And Sumnima, also over the weekend, there were reports of a baby born in the rubble, its cries heard under that tangle of debris. I mean, this is a truly incredible story.

UDAS: That's right. Over the weekend, the rescue workers heard the cries of a wailing baby. And as they followed those cries, they found the mother had actually given birth to that child underneath that rubble. And the baby was still attached to the mother with the umbilical cord. And both the mother and the baby were rescued. We understand that they are still -- they are fine and they've been taken to the hospital. So amazing stories, hopeful stories as well coming out of all of this, Kristie.

LU STOUT: And we have to talk about accountability and justice after this. We know that arrests have been made, including that of the building's owner after he tried to make a run to the border, but was ultimately caught. But what will be done to prevent this tragedy from happening ever again?

UDAS: Well, that's what a lot of people are asking now and the government has said that a separate authority will be set up basically to enforce the violation of building codes. And this authority will be set up soon because of that building collapse.

So the prime minister of the country herself has said that more than 90 percent of the buildings in Bangladesh are actually in violation of the building codes, that's a huge problem. And the main issue really is the complete lack of enforcement.

What normally happens, and this certainly seems to be the case in -- with this building as well, is that the contractors get approval to build a certain -- to build a building to a certain height, but then they keep adding more floors illegally. And that seems to have been the case with this particular building as well -- Kristie.

LU STOUT: Thank you for giving us the latest on the investigation right there.

Sumnima Udas, live for us from CNN New Delhi, thank you.

Now human rights watch is calling for stricter labor laws in Bangladesh. And we spoke to its Asia advocacy director John Sifton about how the tragedy could affect the economy.

(BEGIN VIDEO CLIP)

JOHN SIFTON, ASIA ADVOCACY DIRECTOR, HUMAN RIGHTS WATCH: There is a little bit of a blowback in the consumer retail market. And there's also some corporate responsibility ethics that these corporations hold dear. And so they're starting to realize, you know, we can't just have another tragedy one after another. We'll start to pull back and go to another country which can provide, yes, cheap labor, but also make sure the buildings don't collapse or burn down or what have you.

So I think as those leaders realize that, they will recognize that they can't just squeeze workers and that they have to provide them living wages and safe working environments.

(END VIDEO CLIP)

LU STOUT: Now Sifton of Human Rights Watch, he said that there were just 18 government inspectors for about 100,000 factories in Dhaka alone.

Now an explosion in the capital of the Czech Repulic Prague has injured at least 55 people. That's according to the city's fire department. And state run TV says it it believed that gas caused the blast. It happened in the center of the city.

Now for more on this, we're joined on the line by Marek Cihak. He is a reporter with NOVA Tv in Prague.

And Marek, first tell us more about the site of the explosion and just how devastating this blast was.

MAREK CIHAK, NOVA TV REPORTER: Hello. So, we can say that it was really the most destructive blast in the Czech Republic in the last few years. There was really a powerful explosion and now I am standing in the front of the National Theater. We have to say that the explosion occurred near the National Theater near Divadelni Street, which is the street situated in the city center. It is full of tourists, full of offices. And the blast occurred in the building where an art gallery is situated and some offices from traveling area.

So this is actual information about -- about the place where it occurred.

LU STOUT: Now this explosion, it took place near the National Theater there in Prague. Can you give us an update about the casualty count. How many people were injured as a result of this explosion? And if there was rubble, could there be people trapped in the rubble?

CIHAK: OK. So according to last information up to 35 people were injured, one of them seriously. But in most cases, there are bruises and cuts from glass.

But, of course, there are fears that maybe three people are still -- still buried in the rubble. So rescuers are working in the area which is strictly closed. And we have to wait for another information.

LU STOUT: Now, I know that state media has been saying that this explosion is believed to have been caused by a gas leak. Are you smelling gas in the area? Did eyewitnesses smell gas in the area before the blast?

CIHAK: OK, so I have to say that I don' smell -- I don't smell gas, but according to investigation it's true that maybe it was caused by natural gas. But it's -- I can't smell it now, so...

LU STOUT: OK. Well, pretty soon we're going to learn more details about the cause of this explosion that has injured dozens of people.

Marek Cihak of NOVA TV, thank you so much for joining us on the line and giving us the very latest on this blast there in Prague.

Now, in Libya, armed me in trucks are surrounding the foreign ministry building in the capital Tripoli for a second straight day. They say that they will not move until their demands are met, including the passing of a law that bans Gadhafi era officials from holding government positions.

Now Syrian prime minister Wael al-Halqi is said to be unharmed after a car bomb apparently targeted his convoy in the capital of Damascus. This is the aftermath of that explosion. An opposition group reports that one person was killed in the blast.

It happened in a neighborhood in southwest Damascus. No one has claimed responsibility.

A prominent U.S. lawmaker is pushing the White House to do more to stop the bloodshed in Syria. Now recent U.S. intelligence reports suggests Syrian President Bashar al-Assad's government has used chemical weapons on a small scale. President Obama says the latest evidence is too preliminary to draw any firm conclusions, yet previously stated that Syria would be crossing a red line if it used chemical warfare. Now Senator McCain had this to say on NBC's Meet the Press.

(BEGIN VIDEO CLIP)

SEN. JOHN MCCAIN, (R) ARIZONA: Our actions should not be dictated on by whether Bashar Assad used these chemical weapons or not. First of all, sooner or later he most likely would in order to maintain his hold on power. But what has happened here is the president drew red lines about chemical weapons thereby giving a green light to Bashar Assad to do anything short of that, including Scud missiles and helicopter gunships and air strikes and mass executions and atrocities that are on a scale that we have not seen in a long, long time.

(END VIDEO CLIP)

LU STOUT: Now Senator John McCain there.

Now Syria's civil war has gone on for more than two years now killing an estimated 70,000 people.

Now more cuts in Greece and more protests as well. On Sunday, parliament passed a bill that paves the way for the firing of 15,000 government workers. It's part of the conditions in place for Greece to get its next chunk of cash from the troika of international lenders. But with unemployment above 27 percent, many Greeks are not happy.

You're watching News Stream, and still ahead one of the few symbols of inter-Korean cooperation is close to being completely abandoned.

And iTunes turns 10. Apple's digital media store changed our lives a decade ago, but can it dominate the decade to come?

(COMMERCIAL BREAK)

LU STOUT: Welcome back. You're looking at a visual rundown of all the top stories on this Monday's News Stream. And earlier we told you how crews are now using heavy machinery to remove pieces of a collapsed factory building in Bangladesh. Now later on we'll explore a deleted Instagram account that sources say belonged to Boston Marathon bombing suspect Dzhokhar Tsarnaev.

But now we turn our attention to the Korean peninsula. Now the last 50 South Korean workers at the Kaesong Industrial Complex are still waiting to leave. They had been scheduled to depart the joint Korean facility hours ago. The Unification Ministry has not provided details about the delay.

On Saturday, 126 workers drove back to South Korea. The factories have been idle for about three weeks, that's when Pyongyang pulled out its citizens and later rejected Seoul's offer to hold talks on Kaesong.

And one South Korean military officer tells the Yonhap news agency that the North may heighten military tensions once the industrial zone is clear.

Meanwhile, North Korea says it will put a U.S. citizen on trial soon. Now Kenneth Bay faces the death penalty for allegedly trying to overthrow the regime of Kim Jong un. Now Bay was arrested last November along North Korea's border with Russia. Now Bay, also known by his Korean name Pae Jun-ho was a Christian activist leading a tour group.

North Korean media says he has confessed to the unspecified crime. And analysts warn Pyongyang may try to use Bay as a bargaining chip to gain high level talks with Washington.

But no one knows what North Korea will do next. And tensions may subside when the U.S. and South Korea complete their annual joint military drills on Tuesday. Seoul has moved to modernize its armed forces and will unveil a supersonic fighter jet in the coming months.

Our Anna Coren was invited to take a training flight in this, a T-50 Golden Eagle. But first, she has to pass a tough test. It took place under the close scrutiny of South Korean air force trainers and a medic who could instantly stop the test at the first sign of any threat to Anna's well being.

(BEGIN VIDEOTAPE)

ANNA COREN, CNN INTERNATIONAL CORRESPONDENT: It's not every day you get an opportunity to go up in a fighter jet. But that's what I've been offered by the South Korean Air Force. There is, however, a catch.

I'm ready.

I have to pass a series of tests at the aerospace medical training center that involve withstanding extreme G-forces in the simulator.

The key to enduring this force is a special breathing technique.

UNIDENTIFIED MALE: 1, 2, 3 -- OK.

COREN: Something I'm having real difficulty with.

After a quick practice, it was time for the real thing.

Within seconds I black out.

The problem is I have to reach six Gs. That's six times the force of gravity against my body. And I must hold it for 20 seconds.

(on camera): And I have to do it for 20 seconds. How am I going to do it for 20 seconds?

COREN: My instructor decides to let me watch the footage to see what I'm doing wrong.

(on camera): Oh my god. So I've just seen myself black out twice.

(voice-over): Then it's back to the simulator.

(on camera): This is going to be my third and hopefully my final time. We're getting up to five Gs instead of six Gs, because I've blacked out twice now and it's not a good feeling. So hopefully, hopefully I've got my breathing down pat and we might pass this time.

UNIDENTIFIED MALE: Are you ready?

COREN: Yes.

UNIDENTIFIED MALE: Let's start.

Stand by.

Can you hear me?

COREN: Yes.

UNIDENTIFIED MALE: That's it.

(CHEERING)

COREN: Let's try six Gs.

UNIDENTIFIED MALE: You ready?

COREN: Yeah.

(voice-over): This is the test I need to pass.

UNIDENTIFIED MALE: four Gs, six Gs.

Yeah, pass.

Good. Good job.

COREN (on camera): I was seeing stars, but it was like come on, come on. Thank you. I am happy. I am happy I have overcome my fear. I was honestly terrified, but I worked it out, sort of worked out the breathing. I was seeing stars at one stage, but just had to keep going. So that now means that we can go up in the fighter jet, go at six Gs, is that right? Yes. So, all good.

LU STOUT: Anna did it, so you've got to tune in to CNN on Tuesday. And we'll show you Anna taking to the skies and breaking the sound barrier. That's in part two of her exclusive report.

Now a Boeing 787 took off in Japan for the first time in several months on Sunday. The All Nippon test flight went off without a hitch. And Japan is the latest government to approve Boeing's battery fix after all 50 aircraft around the world were grounded.

Diana Magnay has more.

(BEGIN VIDEOTAPE)

DIANA MAGNAY, CNN CORRESPONDENT: A serene test landing for Boeing's Dreamliner 787, the first time it's touched down on Japanese soil since the aircraft model was grounded three months ago because of battery problems.

YUICHI MARUI, ANA 787 CHIEF PILOT (through translator): I'd be lying if I said I wasn't nervous at all, but I was trying to operate as I always do. It was great weather. Fuji looked beautiful. And I was very happy this day came.

MAGNAY: Boeing still doesn't know what caused the batteries to overheat, one starting a fire in a stationary plane, another forcing the pilot to make an emergency landing after smoke began to fill the cockpit. But Boeing says a solution has been found. It's time to move on.

RAY CONNOR, CEO, BOEING COMMERCIAL AIRPLANES: I speak for all of us that we would put our families on this airplane any day of the week and at any time.

UNIDENTIFIED MALE: If something happened, the enclosure would contain that and then there's tubing that goes off the back of the box.

MAGNAY: Engineers say the new modified batteries run at lower temperatures and are encased in steel to contain and isolate any overheating.

MIKE SINNETT, CHIEF PROJECT ENGINEER 787 PROGRAM, BOEING: We've provided layers of protection so that no matter what the initiating cause was, it will have no effect on the airplane because the enclosure that we've designed.

MAGNAY: Aviation authorities in the U.S., Europe and Japan have given the go ahead. Now, Boeing engineers are installing the new redesigned batteries on all of the affected planes.

Three months in the making, Boeing certainly hoping that these modifications make the new battery safe enough, but is safe enough good enough? Boeing certainly gave the impression that it wouldn't be using the lithium ion battery on any future model it might develop.

Ethiopian Airlines was the first to resume commercial operations on Saturday just two days after the U.S. Federal Aviation Authority said the planes were fit to fly.

Japan's two main carriers, ANA and Japan Airlines are more cautious. They'll test the planes for now. If all goes according to plan, they'll fly passengers again in June.

Diana Magnay, CNN, Tokyo.

LU STOUT: You're watching News Stream. And the L.A. Lakers have been sent packing from the playoffs. You're sports update is next.

(COMMERCIAL BREAK)

LU STOUT: Coming to you live from Hong Kong, you're back watching News Stream.

Now we know now the first two teams through to the second round of the NBA playoffs. And for one famous franchise, it is the end of the road.

World Sport's Alex Thomas is standing by with all of the details -- Alex.

ALEX THOMAS, CNN SPORTS CORRESPONDENT: Yeah, hi, Kristie. Only the Celtics have been crowned NBA champions more times than the Los Angeles Lakers. But having scraped through to the postseason it was the end of the road for Ameirca's famous West Coast team in Sunday's playoff games. They were put out of their misery by the San Antonio Spurs.

Tony Parker, outstanding for the visitors -- take a look at this acrobatic lay-in, part of his 23 points and four assists on the night. San Antonio outscoring the Lakers in every quarter.

Here is a big slam from Danny Green as the Spurs stretch their lead to 21 points.

With the injured Kobe Bryant on the sidelines there was no hope of a miracle comeback. Now the debate starts about the changes the Lakers need to make. 103-82 win puts the Spurs into the second round of the playoffs.

(BEGIN VIDEO CLIP)

DWIGHT HOWARD, L.A. LAKERS FORWARD: This is like a nightmare. It's like a bad dream. And I couldn't wake up out of it, you know. That's what it felt like, you know, just seemed like nothing could go right from the start.

MIKE D'ANTONI, LAKERS HEAD COACH: Stuff happens. It's a kind of a year that was all upside down. And, you know -- but I appreciate the effort they gave to get us in the playoffs and then they just didn't have it.

PAU GASOL, L.A. LAKERS FORWARD: We've done our best. We've done our best. We fought our way through it. We earned to be in the playoffs after everything that the team has been through and being pretty down in the standings, you know, and we pretty much didn't have a whole much of a chance against the Spurs.

(END VIDEO CLIP)

THOMAS: Well, and the Heat was the other team through to the conference semifinals. The reigning NBA champions have played like the title favorites they are. LeBron James with 30 points in this one as they match the Spurs 4-0 series sweep by beating the Milwaukee Bucks 88-77 in game four on Sunday night.

Gareth Bale has strengthened his reputation as one of the most talented young footballers in Europe. He's become the first since former Manchester United star Christiano Ronaldo be voted both footballer and young footballer of the year by his fellow professions in England's Premier League. Bale scored 24 goals for Tottenham this season so far, however that tally doesn't quite match Robin Van Persie's. The former Arsenal striker converting the penalty against his former side to salvage a 1-1 draw for England's new champions Manchester United. It was his 25th Premier League goal of the season.

Earlier in the game, Arsenal opened the scoring through Theo Walcot as they battle with Chelsea and Spurs for a Champion's League qualifying place.

Rafael Nadal's French Open preparations are back on track after recording his fourth tournament win of the season. A week after losing his eight year unbeaten streak at Monte Carlo, Nadal reached a sixth successive final since returning from injury taking on fellow Spaniard Nicolas Almagro for the Barclona Open title.

Almagro has never beaten Nadal, so it was a surprise when the world number 12 raced into a three games to love lead. But the top seed recovered, taking the opening set by 6-4. Some spectacular tennis on the way. Nadal clinching his eighth title in nine years at this event with a straight sets victory in 13 finals against his countryman. Nadal has never been beaten.

Before we go, there are reports that NFL star Tim Tebow has been released by the New York Jets. We're looking into this for you and we'll have more in World Sport in just over three-and-a-half hours time, Kristie.

LU STOUT: All right, Alex Thomas there, thank you.

Now we are looking for clues on the Boston bombing suspects internet accounts. And still ahead right here on News Stream, we'll tell you about one of Dzhokhar Tsarnaev profiles. It was apparently deleted before the attack.

And later, it's been a decade since iTunes started selling music on the net. But with streaming services and all the competition, can it last another 10 years?

Now the prime minister of Bangladesh has visited the site of a building that collapsed near Dhaka last week to see the devastation firsthand. Heavy machinery is moving into place to shift the debris. Nearly 400 people were killed when the building came down five days ago. Many more are still missing. Now the owner of the building and five others have been arrested.

Fire department officials say at least 55 people have been injured in an explosion in the Czech capital of Prague. State TV is reporting that it was a gas explosion. Authorities say the first floor of one building was destroyed in the explosion and windows were blown out in nearby buildings.

The surviving suspect of the Boston Marathon bombings is being held in a small cell at a prison medical facility some 60 kilometers outside Boston. A spokesman says Dzhokhar Tsarnaev is speaking and interacting with medical staff. The 19-year-old was charged with using a weapon of mass destruction in the April 15 attack, which killed three people and injured more than 260 others.

Meanwhile, there is new information coming out of Russia in connection to the Boston bombings. Our Nick Paton Walsh has also spoken again to the parents of the suspected Boston bombers and has new details from our bureau in Moscow.

So Nick, first tell us what you've learned from the parents. What did they tell you?

NICK PATON WALSH, CNN INTERNATIONAL CORRESPONDENT: Well, I spoke to both parents in the last couple of hours. And it was quite clear from speaking to the father very brief, very strained conversation. He said simply I'm sick. I am sick.

The mother, more details. She of course confirmed his bad condition, his connection I believe with high blood pressure. But he does appear to be shaking as well. There are obviously major concerns for his health. Travel plans keep changing.

She made it clear he's not in any condition to travel great distance, particularly to the United States at this particular point.

She also said that she, herself, would be willing to go to the United States only if it was made clear to her she could see Dzhokhar. And she said she wasn't really bothered about the potential outstanding charges for shoplifting, suggestions about that, but also given how this investigation is widening and potentially accusations are being lobbed in her direction, she said she would still go regardless of these potential risks.

But clearly a parent under great strain here. Both sounding absolutely exhausted. Their travel plans constantly changing. That U.S. trip most certainly delayed -- Kristie.

LU STOUT: And separately, Nick, and we don't know if this is related, Russian special forces have killed a member of a militant group in Dagestan. What can you tell us.

WALSH: This is a man called (inaudible). Now he is a member of a militant group headed by a man called Abu Dujan. And the pictures you'll see now of a very violent special forces raid in the early hours of yesterday morning. Police have confirmed (inaudible) was killed in this particular attack.

How does it relate to the Boston bombings? Well, Abu Dujan was killed in December, also by Russian special forces in a similarly violent encounter. He was a man to whom Tamerlan Tsarnaev linked to a video of from his YouTube channel. So there's the link between Tamerlan Tsarnaev and Abu Dujan.

We don't know if they met or if he was just simply interested in his preachings online, his statements online. But we do know (inaudible) has been killed in the last 24 hours, 48 hours, in Dagestan by Russian special forces.

So it's absolutely clear that Russian special forces and security services are on the trail of the Abu Dujan group as we speak, we just don't know if that is related to any information they're passing to the FBI at the moment -- Kristie.

LU STOUT: And you've also been following this growing debate about what Russian authorities knew about the Tsarnaev family years ago and didn't tell the U.S.

WALSH: Well, it is clear from I think everyone's perspective the Russians did repeatedly warn the U.S. about Tsarnaevs. Now, what is not clear is how much information they gave back when the FBI requested more detail. That's when the exchange appears to have slowed.

There has been information passed across in the past few days relating to a wiretap which appears to implicate the mother, according to U.S. officials, talking about jihad, discussing jihad with one of her sons. We don't quite know whether that's incriminating or simply a discussion of completely different form.

The point here, really, is the debate diplomatically will continue to be who knew what when. We're not heard an open transparent public version of events from the Russians. That could be because they're still hunting down people in Abu Dujan's militant group. It could be because they think these exchanges are best done privately. Certainly, the American side of things leaks an awful lot more.

But you're going to see, of course, a lot of pressure from congress on Capitol HIll, to work out who said what, when. A lot of pressure on the Russians and of course an easy get out for the FBI for standing accused of dropping the ball to claim that enough information from the Russians.

But certainly those years ago there were repeated warnings, it's just not clear if the information kept flowing once the FBI decided there wasn't much to investigate -- Kristie.

LU STOUT: Now many, many different threads to this story. Our Nick Paton Walsh across it all, thank you very much indeed, Nick.

Now investigators are also scouring Dzhokhar Tsarnaev's online footprint. They're looking at his accounts on Twitter and the VK Russian social networking site. But there is one online profile that's proved a little bit harder to find. CNN Money's Laurie Segall has more.

(BEGIN VIDEOTAPE)

LAURIE SEGALL, CNN TECH CORRESPONDENT: A deleted Instagram account sources say belonged to Dzhokhar Tsarnaev. Unlike the rest of his digital life, it hasn't gotten much attention since his arrest. Close friends say Dzhokhar used the name J Miester, but it was removed before the April 15th bombing.

But a digital trail shows images that he liked in the past. Several include references to Chechnya that are marked with dozens of hashtags. One shows a Chechnan warlord who masterminded terrorist attacks against Russia and but was killed in 2006. Several show Dzhokhar interacting with other users. An expert on Chechnya says is shows an understanding of Chechnya and its struggle for independence from Russia.

The close friends tell CNNMoney from what they saw he used Instagram for social purposes. So how are we able to resurrect them? Here is how it works

SAM ALTMAN, PROGRAMMER/TECH ENTREPRENEUER: So, we're looking at a photo from Instagram on a site called Statagram, and this is the copy as it existed on the web today. We can see that these users, these 19 users have liked it, and we can see there are six comments on the photo. Here are the hashtags.

However, we can also go back in time, thanks to the Google web cache. Here is other data around that back from April 10th of the same photo. So, we can see there is the same six comments there are today. And here is a list of users that like the photo, most of which are already on there and there have been new ones since April 10 that have liked it as well. But there is one that liked it in the April 10th version of the page, jmeister1 that is not you can see on the current version.

SEGALL: Law enforcement experts like Julitette Kayyem say the deleted account is likely to get a close look from investigators.

JULIETTE KAYYEM, CNN NATIONAL SECURITY ANALYST: If I were an investigator right now, obviously the platform he deleted matters the most. Were there clues embedded in the combination of images that can tell us something about what Dzhokhar was thinking? Because some of those pictures are very benign, some of them standing alone don't mean anything.

SEGALL: Digital footprints continue to get bigger as people become more and more willing to put their lives online.

Laurie Segall, CNN Money, New York.

(END VIDEOTAPE)

LU STOUT: You can find out more about that story online. Just click on to our website CNN.com/international. There's also of course more about the investigation and the prison medical facility where Dzhokhar Tsarnaev is being held.

Now time now for your global weather check. There is heavy rain in the Middle East, in particular Saudi Arabia and the Gulf region. For more, let's go straight to our Mari Ramos -- Mari.

MARI RAMOS, CNN WEATHER CORRESPONDENT: Hey Kristie, yeah, this is something that's been going on for several days already. And it's unusual in its scope as two different things. First of all, its been very heavy rainfall. And the second thing is that it's somewhat out of season, you could say, because even though the rainiest months of the year -- January, February, March, in that order -- it does tend to rain in April, just not as much as what they've had recently.

And I want to show you a couple of pictures from the region.

Oman has been one of the hardest hit areas, particularly in the north. It began raining in Oman I think on Wednesday, so we're already four or five days into this. And it has taken quite a toll on the region. There are many areas that are completely blocked off because of the high water. Authorities asking people to not travel if they don't have to. There are many roadways, like I said, that have been blocked off, covered in water.

Most of the deaths that have occurred, at least 10 across the entire region, have been people drowning in their vehicles or car accidents, because a lot of people of course not accustomed to driving on the wet roadways here.

The other things is, some areas have been left without power. And any amount of rain that falls could really cause some additional flooding. So we're very concerned about this.

I want to show you this satellite image right now. And you can see it again the rain and thunderstorms popping up in areas right over here across Saudi Arabia, in the interior portion. And this is going to be one of the areas to watch.

But even as we head back over here, notice again the thunderstorms popping up across Oman, back over toward the UAE, and even Abu Dhabi has had some rains over the last 24 hours, not as much as before, but like I said it does continue to rain across this area.

Then the rain kind of switches and it continues to move on into southern parts of Iran and maybe even into Pakistan, but the bulk of it again will be in this region right in here, so that's still going to be a concern.

The temperatures have been a little bit cooler, of course, because of the cloud cover, below the average in many cases in Muscat, because of all the rain that you've had. For example, you had 27 degrees for your daytime high. Your average is 35. So you can really see what the rain is doing here.

As far as the forecast, well this is what we have. The rain, this old frontal boundary will kind of remain along this area here bringing us the possibility of more wet weather. So this is still going to be a concern across the region.

So, from here, I want to take you to Europe. A little bit of different story, so we're going to go ahead and switch gears, because I just like sharing these pictures, Kristie. Let's go ahead and take a look. This is from Sicily. This is in -- near Catania. We are talking about Mount Etna erupting yet again. It is the most active volcano in Europe. The 3,300 meter stratovolcano, which basically refers to the type of volcano that it is, has erupted yet again. These pictures are from the weekend. There's not danger to the population that is nearby. There were a few travel delays at the airport there. But it has reopened.

And what's amazing, Kristie, the type of eruptions that Mount Etna have are actually considered small eruptions on the volcano scale. I can't imagine a big one. Back to you.

LU STOUT: You know, those pictures truly awesome in the pure, nontrendy sense of the word. Just awesome. Mari Ramos, thank you so much for the share and take care.

Now let's look back at our video rundown. Earlier, we brought you the latest on the South Korean workers at the Kaesong Industrial Complex. And in a CNN exclusive, we saw my colleague Anna Coren bravely training to fly South Korea's new supersonic jet.

But now to tech news. And Apple's iTunes music store has just turned 10. The digital media store, it launched on April 28, 2003. And now it sells TV shows, movies, apps and books, but back then it only sold music. And its arrival marked a sea change for the recording industry.

Since the introduction of iTunes, music sales have plummeted in the United States. It went from nearly $12 billion in 2003 to just over $7 billion last year. And that's because iTunes made it possible for people to download their favorite singles for a cheap price instead of buying more expensive CDs.

Now iTunes became the largest music retailer on the planet by 2010. And according to NPT estimates, iTunes is currently responsible for 63 percent of all digital music sales. That puts it well ahead of newer competitors like Amazon and Google.

But another threat has emerged in the form of internet radio. So what does the next decade hold for iTunes? Nilay Patel is the managing editor of the tech blog The Verge. And he joins us now live from CNN New York.

And Nilay, 10 years on, we went to the stats just then, iTunes is still the leader of the digital music pack, but are the cracks starting to show?

NILAY PATEL, MANAGING EDITOR, THE VERGE: You know, I think they are. I think a lot of the power that iTunes had at the beginning was the really tight lock-in it had with devices like the iPod and, you know, the early versions of the iPhone. But if you look at how people are starting to buy and consume music now, there is a bigger shift ongoing to subscription services like Spodify, Rdio, and Apple itself is being, you know, rumored to be working on deals to launch its own streaming service in the future.

And so iTunes as a program that you run on a desktop computer that you plug a phone in over a wire and sync music over USB, that model is starting to kind of fade away. And iTunes itself needs to change to be more of an internet centric service. And they're already starting to do that, you know, with iTunes in the cloud which takes all the music from your computer and puts it in the cloud and sends it down to you.

But they need to move the entire hub of iTunes up to the cloud and start streaming music to you to compete with upstarts like Spodify and Rdio.

LU STOUT: Yeah, you mentioned Spodify, Rdio, these subscription upstarts that are rivals to the iTunes Music Store, but of these top subscription streaming services out there, no one has really reported big profits yet. So is that the winning strategy at the end of the day?

PATEL: You know, there is a big debate whether people want to own their music, or whether they just want to buy access to music. And when iTunes launched 10 years ago, Steve Jobs said on stage and said very confidently people just want to own their music, which I think is a model that's rooted in having physical media in your life -- you know, CDs, LPs, whatever. But I think that's starting to change. I think if you look at, you know, habits, especially among the young, most kids are getting their music off of YouTube, right. They're going to Vivo, they're going to just Googling it and hitting play on the first service they can see.

So the idea that they want to own something physical is starting to go away.

And music more than any other kind of media is very retail based. It's very consumer driven. So when consumer habits change, the services have to change. That's very much unlike something like TV or movies, right, a movie production company sells a movie to a studio which sells a movie to HBO and a theater and a TV station. And so consumer habits, you know, when you buy cable, they don't affect all the way back to how movies are made and sold, but when you change your consumption habits as a music consumer it changes the market immediately.

LU STOUT: Now there is suddenly Apple music buzz out there that Apple will launch iTunes Match, this $25 a year cloud music locker. There's also the rumor that Apple is going to launch a new music streaming service nicknamed if it happens iRadio.

Your thoughs on those announcements. And if they do happen, will it be enough to draw the new fans, especially the younger demographic?

PATEL: You know, well -- so iTunes Match is already launched in the United States. You know, they're rolling it out around the world. And they gained a lot of credibility in the music business for doing it in quote, unquote, the right way. So Google and Amazon launched similar services without appropriate licensing deals in place. And the nature of the copyright law in the United States is that you don't need the deals you can just do it. But that doesn't mean you're not going to irritate the music companies.

Apple waited until they had the deals, then they launched the service, and they gained a lot of goodwill.

The next step is for them to say we're going to launch a radio service, a streaming service that can go against Pandora, Spodify, Rdio, but they're big holdup right now is they're asking for licensing rights that are much lower than what those companies are paying. And they're saying, look, we're Apple. We have the iPhone, we have iTunes, and our volume will sell so much more music that we'll pay a lower rate, but you'll make more money.

That's a pretty classic negotiating tactic. A Steve Jobs maybe would have pulled it off. He had the sort of charisma and gravitas to walk into the music companies and say this is what I want and get it. Apple's real challenge is doing that without that sort of personality at the helm.

LU STOUT: All right. Nilay Patel of The Verge, thank you so much for giving your thoughts on the iTunes music store 10 years on and what it could look like 10 years from now. Thank you and take care.

You're watching News Stream. Still to come on the program, we take a look at the world's most advanced bionic arm. So advanced it is powered by thought alone. That's just ahead in our new art of movement series.

(COMMERCIAL BREAK)

LU STOUT: Welcome back.

And here on News Stream, we keep a close eye on the latest innovations in science and technology. And in May, a new show is launching here on CNN exploring how those cultural currents are shaping our lives.

The Art of Movement will showcase everything from ballet to bionics. And today, we want to give you a taste of that.

Nick Glass travels to Johns Hopkins University in the U.S. State of Maryland to take a look at the world's most advanced bionic arm.

(BEGIN VIDEOTAPE)

NICK GLASS, CNN CORRESPONDENT: So this is your bionic arm?

MICHAEL MCLOUGHLIN, JOHN HOPKINS UNIVERSITY APPLIED PHYSICS LABORATORY: Yes. We call this the modular prosthetic limb, or MPL.

This is the most sophisticated arm in the world. It can do virtually everything that your natural limb can do.

GLASS: That's quite a claim.

MCLOUGHLIN: Yes, it is. This arm has 26 individual joints that we can control.

GLASS: Has there ever been an arm quite like it?

MCLOUGHLIN: Never. So this arm is intended to work with your brain just like your natural arm works.

GLASS: Johnny Matheny from West Virginia worked in the baking trade until he lost his left arm to cancer in 2008. He heard about the bionic arm and signed up as soon as he could.

The bionic arm weighs much the same as a normal one, about nine pounds. And it can mimic pretty much anything a normal hand can do, has almost the same dexterity. 26 joints, 100 senors as we've been told, also 17 motors and a tiny computer built into the palm of the hand. The effect is almost musical.

And, what's it like?

JOHNNY MATHENY, PATIENT: I mean, to actually be able to work a hand just like you had. I mean, in 2008 when he took the arm I never figured I'd never have another actual hand. I'd seen the hooks and I figured that's exactly what I'd be getting. And then they come out with this and it's like wow.

GLASS: The arm has to be carefully programmed on computer, coded to respond to electrical impulses to Johnny's stump. He thinks about moving his old arm. You can see the impulses on the screen, little waves and squiggles. The computer recognizes each pattern and makes the bionic arm move accordingly.

At the beginning, did Johnny believe it would work?

MATHENY: Well, you know, you believe it, but there's always, you know, that little bit of doubt that you know it's not going to work. And when it did it was like whoosh, yeah, I was ready. Give me more. Give me more.

GLASS: It was time to have a go myself, to slip on a special glove with sensors linked up to the bionic arm.

How like my real arm and hand is this?

MCLOUGHLIN: It can do virtually anything that you can do with your natural hand, OK. And you can more your wrist, right, it's very fluid.

GLASS: My goodness, I could wave like the queen.

MCLOUGHLIN: That's right.

You can think about things like, you know, playing the piano eventually, doing very complex types of things.

GLASS: You imagine someone with bionic arms playing the piano?

MCLOUGHLIN: I think we'll get there someday. We're not there yet, but we'll get there.

GLASS: Do you feel privileged?

MATHENY: Oh, yes, very privileged, very privileged to be able to do this, to show you know any upper amputee person, you know, what they'll be able to do. It's going to be what's coming their way. It's not going to be, you know, the way of the future, the future is coming now.

LU STOUT: Remarkable innovation. Nick Glass reporting there.

Now nearly four years after the death of pop superstar Michael Jackson, a wrongful death trial is getting underway in Los Angeles and we'll tell you what's at stake.

(COMMERCIAL BREAK)

LU STOUT: Welcome back.

And nearly four years after the death of Michael Jackson, the pop superstars final days will play out again in a Los Angeles courtroom.

Now only hours from now opening statements are set to begin in a wrongful death trial. Jackson's mother and his three children are suing concert promoter AEG Live in connection with his death. Casey Wian has more.

(BEGIN VIDEOTAPE)

CASEY WIAN, CNN CORRESPONDENT: Michael Jackson was in the last weeks of rehearsal for what was to be his grand comeback. The exhausted, 50- year-old insomniac died in 2009 from an overdose of sedatives and the surgical anesthetic propofol.

Dr. Conrad Murray was convicted of involuntary manslaughter for giving Jackson the fatal dose in an effort to help him sleep. He's in prison.

Now the company that promoted the comeback tour, AEG Live, is fighting legal claims by Jackson's mother and children that it shares responsibility for the singer's death because it hired and supervised Murray.

PIERS MORGAN, PIERS MORGAN TONIGHT: What do you think, as his mother, caused his death?

KATHERINE JACKSON, MICHAEL JACKSON'S MOTHER: I don't know. All I know is they used propofol and they shouldn't have used it and they used it in the wrong setting, that's all I know and that's what caused his death.

PROF. JODY ARMOUR, UNIVERSITY OF SOUTHERN CALIF. LAW SCHOOL: The gist of the plaintiff claim against AEG is that you controlled Dr. Murray and you used your control over Dr. Murray to pressure him into taking unnecessary and excessive risk with his patient Michael Jackson leading to Michael Jackson's death.

WIAN: AEG Live's attorney says there was never a signed contract with Murray and that Jackson was the only one who controlled him.

MARVIN PUTNAM, AEG ATTORNEY: He was chosen by Michael Jackson to be there at Michael Jackson's behest. He'd be Michael Jackson's doctor alone, but this was only being done because Michael Jackson asked for it. Michael Jackson was the only person who could get rid of him at will.

WIAN: Potential witnesses include Jackson's teenaged children, Prince Michael and Paris. Producer Quincy Jones could testify about the billions of dollars Michael Jackson would have earned if he had lived, money his heirs now want from AEG, a multibillion sports, entertainment and real estate conglomerate.

The trial is expected to last between two and four months. Jackson family attorneys would like to call Conrad Murray to the stand, but if they do he plans to take the fifth so as not to jeopardize the appeal of his manslaughter conviction.

LU STOUT: The annual White House Correspondents' Dinner was held over the weekend, also known as Nerd Prom, it's an event where politicians and the journalists who cover them, get together for dinner and laughs. And few escaped President Barack Obama's standup comedy, including himself.

(BEGIN VIDEO CLIP)

BARACK OBAMA, PRESIDENT OF THE UNITED STATES: I understand second term, need a burst of new energy, try some new things and then my team and I talked about it we're willing to try anything, so we borrowed one of Michelle's tricks.

CONAN O'BRIEN, HOST, CONAN: And seriously Mr. President, your hair is so white it could be a member of your cabinet.

(END VIDEO CLIP)

LU STOUT: Oh, dear.

Oh, the hair jokes. Nobody was safe.

We should probably add that Mr. Obama also poked fun at CNN. He said that he admired our, quote, "commitment to cover all sides of the story, just in case one of them happens to be accurate."

And that is News Stream, but the news continues at CNN. World Business Today is next.
